Reducer - with one plug-in end - N - 76,1-42mm IVAR.IVN12

Product detailed description

This stainless steel reducer is commonly used in residential and commercial buildings for connecting different pipe sizes in heating, sanitary, and industrial systems. It is suitable for applications such as fire sprinkler systems, solar installations, and pressurised air systems. The plug-in design allows for secure and leak-free connections, particularly in environments where thermal expansion and contraction are common. The EPDM O-ring ensures sealing integrity across a wide temperature range, making it ideal for both indoor and outdoor installations.

Installers working on HVAC systems, water supply lines, and industrial piping will find this reducer essential for adapting pipe diameters. The material and design are selected to withstand mechanical stress and chemical exposure, ensuring long-term reliability in diverse operating conditions.

Technical parameters

Material	Stainless steel grade Wst. Nr. 1.4404 (AISI 316L), O-ring EPDM
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN12.7642
Brand	IVAR

The operating temperature range of -20°C to +85°C allows use in both cold and warm water systems. The nominal pressure rating of PN 16 ensures compatibility with medium-pressure applications. These parameters are critical for determining the suitability of the reducer in specific system designs and for selecting appropriate materials in the surrounding piping network.

Installation and connection

The reducer features one plug-in end for a press connection and one end for a direct fit. The press connection requires a compatible press tool and a properly sized sleeve. The plug-in end must be fully inserted until the seating mark is reached. The connection size is 76.1 mm (external diameter) to 42 mm (external diameter). During installation, ensure the O-ring is correctly seated and that the press connection is made according to the manufacturer's specifications. Common mistakes include insufficient pressing force, misalignment, or failure to check the seating indicator. Always verify the connection by checking the seating mark and ensuring no gaps are visible.

Compatibility and accessories

This reducer is compatible with IVAR stainless steel pipes and press fittings of the same material. It is suitable for use with EPDM O-rings in systems operating within the specified temperature and pressure range. Additional components such as press sleeves and tools may be required for installation. No specific related products are recommended for this model.

Technical background for designers

The reducer operates by providing a transition between two different pipe diameters while maintaining a sealed connection. The 1.4404 stainless steel body offers high corrosion resistance and mechanical strength, making it suitable for aggressive environments. The EPDM O-ring provides a flexible seal that compensates for minor misalignments and thermal movement. The press connection ensures a leak-free joint by compressing the sleeve around the pipe. The service life and efficiency depend on proper installation, correct system pressure and temperature, and the quality of the surrounding piping materials.

Service and operation

No regular maintenance is required for this reducer under normal operating conditions. However, it is recommended to periodically inspect the connection for signs of leakage or mechanical damage. If the seating indicator is not fully engaged or the connection appears loose, the fitting should be replaced. No specific service intervals are provided in the technical documentation.
